i s claims. (o1. 91-41) This invention relating as indicated to a target have provided a cabinet I which has in' its front painting device is more particularly directed to a face an opening 2 through which missiles are means for painting targets aswell as the surface adapted tobe projected. This cabinet has an .surrounding said target so that such surface and interior partition upon which a target 3 is sup- 5 the target will always present a neat and sightly ported and such target is surrounded by a surface appearance, 4, it being my intention to provide means to In target games the target itself as well as the maintain such target and surface clean and neat surrounding surface usually presents an unsightappearing at all times. The means for doing this ly appearance due to theimpact of bullets, the comprises a motor 6, brushes 2l and 22 and the l0 net resultfof `which is vthat the game apparatus, mechanism associated therewith.

In this manner the cross bars, such disclosed structure constituting, however, brushes, Ts I9, I5, 23 and 2d and rods 25 and but one of various structural forms in which the 26, are elevated as a unit. y '0 principle of the invention may be used. In order to maintain the brushes 2l and 22 40 In the accompanying drawings: in a substantially vertical position as they rise, a Fig. lis a Vertical section taken on the line I-I guide member 21 is provided with a vertical slot of Fig. 2. 28 therein for the reception 'of the right hand end Fig. 2 is a transverse Vertical section taken on (as viewed in Fig.v 1) of rod 29.

In order to secure a brushing action I have Referring now to the drawings, and-more parprovided a cam 33,'Which is fixed upon the shaft ticularly to Figs. 1 and 2, it will be seen that I 9. This cam engages a lever 32pivoted at 32a 55 and a cable 3| extends from one end of lever 32 and wraps around pulley 3U, which is fixed to shaft 2U. A spring 49 is adapted to connect pulley 36 with the bracket 48. Thus it will be seen that when the rod 20 assumes the dotted line position shown in Fig. 1, the cable 3| becomes taut, whereupon the cam 33 forces the lever 32 downwardly and this pulls the brushes 3| and 32 from a vertical to a horizontal position and finally to an upwardly extending position. In this manner the brushes are caused to move in an arc, much in the manner of manual painting. After the brushes have reached their upper line of movement, as shown in dotted lines in Fig. 1, the spring 49 functions to return the pulley 36 back to its normal rotary position as distinguished from its normal vertical position and thus the brushes go through the same arc in reverse direction.

The pins 5l) and 5| stop cross bar 20 in a position just above the targets 3 and 3a and altho the motor 6 is still running the pulleys i6 and are not rotated due to the slip clutch arrangement, and this holds the paint brushes in position over the targets, At the same time the cam 33 on shaft 9 rides on pedal 32 which alternately tightens and loosens the cable 3|. With each rotation of the cam 33 the pedal or lever is pushed down and thus the cable 3| exerts a pull on pulley 36, which in turn moves cross bar 20 causing the paint brushes to turn up against the metal plate 4. When the high side of cam 33 contacts lever 32 spring 49 is placed under tension and when the low side contacts the lever the spring 49 returns the pulley 30 to its normal position and in doing so returns the paint brushes to a vertical. position. This oscillating movement is prefer ably repeated four times by means of a device which I will now describe.

A slip clutch, shown in detail in Fig. 3, is mounted on shaft 9. The pulley 8 is loosely mounted on such shaft and has an extended hub 42 with a recess therein adapted to receive the sliding collar 46. 'I'he sliding collar 48 contains a pair of axial slots and a pin 4| fixed to shaft 9 is received in such axial slots. This permits axial movement of the sliding collar 40 and thus rotation is imparted to shaft 9 when the sliding collar 40 engages the pulley 42 of the hub 8. A fork |4 pivoted `at |4 to the partition 5 engages a groove 43a in the collar 40 at one end and at the other abuts cam 44 at all times due to the presence of spring 46. Cam 44 is fixedly mounted upon shaft 45 and this shaft has a star wheel 41 mounted at one end thereof. A pin 48 mounted upon pulley 8 is adapted to engage the serrations on the star wheel so that the clutch member 48 and 42 engage and release at predetermined times. Each time the shaft 9 rotates, pin 48 on pulley 8 contacts one tooth on star gear 41 which turns shaft 45 and cam 44 one-tenth of a revolution. When the cam 44 contacts lever 43 it opens the clutch or moves the collar 40 away from hub 42. This permits free action of shaft 9 as the pulley 8 is loosely mounted upon such shaft. When shaft 9 is released the weight of the paint brush assembly is more than sufficient to unwind cables |4 and |1 which allows the paint brushes to return to the paint receptacle 52 and assume the position shown in Fig. l. As the cross bar and paint brush assembly descends it is held in proper position by pin 29 engaging the guide member 21. When the cross bar 22a, which is associated with the paint brushes and cross bar 2U, reaches its lowermost position (shown in Fig. 1) it forces the switch blade 62 downwardly, thus breaking the circuit between lines 61 and 68 shown in the wiring diagram (Fig. 7) and stopping motor 6.

Current is supplied through service lines 60 and 6| and when it is desired to start the apparatus it is merely necessary to push the push button 63. This supplies current to the motor and when the cross bar 22a is lifted spring 69 forces switch blade 62 upwardly, thus making the circuit between contact 66 and contact 1li,` or stated in other words, completing the circuit through lines 6|, 61, 68 and 64.

In order to prevent the paint or coating composition from unduly evaporating and at the same time preventing the paint from splashing, due to particles of lead falling in the paint receptacle, I have employed the means shown `in Fig. 5 which consists briefly of a spring pulled lever 54 fixed to the lid 53 of the receptacle 52. The weight of the cross bars 2U and 22a is more than sucient to overcome the force exerted by spring 55 so that as the brushes descend to the position shown in full lines in Fig. l, the cross bar 22a engages one end of the lever 54, thus closing the lid 53. The cross bars are received in slots 56 and 51 in opposite ends of the receptacle 52. When the cross bars start 4upwardly the spring 55 pulls lever 54 and opens the lid and maintains it open until the brushes have again descended.

From the foregoing description it will be seen that I have provided a means for painting or coating a target and/or a target surface which functions mechanically and closely simulates manual painting. It will also bernoted that it is merely necessary to push a button, whereupon the apparatus is set in motion and a desired number of oscillations may be imparted to one or more brushes. In this connection it is to be observed that the number of brushes is a matter of choice, depending upon the space to be `covered and that I may use two brushes or as many more as is desired. It will also be observed that the number of oscillations imparted to the brushes is again a matter of choice as this may be varied by varying the number of serrations in the star gear 41. It will thus be seen that I have provided an automatic apparatus which at the same time is flexible in that it can be easily changed to meet any of a number of various conditions.
